Abstract
A node device switches from a sleep mode to a wake-up mode when the node device needs to transmit information. The node device transmits a synchronization signal to the another node device based on the information and determines whether an acknowledgement signal is received. The node device transmits the key-frames to the another node device when the acknowledgement signal is received.
Claims16
A node device, connectable with another node device, the node device comprising:
- at least one processor;
- a storage system;
- and
- one or more programs that are stored in the storage system and executed by the at least one processor, the one or more programs comprising instructions for:
- switching from a sleep mode to a wake-up mode when the node device needs to transmit information, wherein the information comprises a synchronizing signal and key-frames;
- transmitting the synchronization signal to the another node device based on the information and determining whether an acknowledgement signal is received from the another node device;
- and
- transmitting the key-frames to the another node device when the acknowledgement signal is received from the another node device.
A node device, connectable with another node device, the node device comprising:
- at least one processor;
- a storage system;
- and
- one or more programs that are stored in the storage system and executed by the at least one processor, the one or more programs comprising instructions for:
- switching from a sleep mode to a wake-up mode periodically according to a wake-up interval;
- responding an acknowledgement signal when receiving a synchronization signal from the another node device;
- and
- receiving key-frames from the another node device.
A communication method, applied in a node device connected with another node devices, the method comprising:
- switching from a sleep mode to a wake-up mode when the node device needs to transmit information, wherein the information comprises a synchronizing signal and key-frames;
- transmitting the synchronization signal to the another node device based on the information and determining whether an acknowledgement signal is received from the another node device;
- and
- transmitting the key-frames to the another node device when the acknowledgement signal is received from the another node device.
